Niobium Nitride(NbN) Micronpowder Main Feature

NbN has a high melting point, typically around 2,507°C (4,545°F), making it suitable for high-temperature applications. It is a type II superconductor with a relatively high superconducting transition temperature (Tc) for a non-copper oxide material. The Tc can vary depending on the stoichiometry and structural quality, but it is typically in the range of 14-16 K (-259.15°C to -257.15°C). This property makes it valuable for quantum computing, superconducting magnets, and other applications where superconductivity at relatively high temperatures is advantageous.NbN micronpowder has a high hardness and mechanical strength, which makes it useful as a coating material for cutting tools and in other applications requiring wear resistance.It exhibits good chemical stability and corrosion resistance, which is beneficial for applications in harsh environments.While it is a superconductor below its Tc, at temperatures above this, it behaves as a conductor with reasonable electrical and thermal conductivity.
